Abstract

Embodiments for a battery charger include a single conversion switched mode power supply having a bias winding on the primary side of the power transformer. The bias winding produces an output that is proportional to the voltage produced on the secondary winding, and is sensed by a programmable voltage sensing circuit. The programmable voltage sensing circuit is programmed by a voltage select signal from the secondary side of the charger to produce an sense signal that is proportional to the output of the bias winding by a selected factor corresponding to a battery type of a battery being charged.
